I have the solution for that, it's logic. First, the healers are to more powerfull, they do a lot of damage AND they can heal. This is not normal. You have two solution for that, decrease their output damages from 30% at least. Or this one: Put a classes limit in every squad. Limit at One Healer and One Jetpack classe. Because jetpack classes are too more powerfull for at the moment, this why everyone take them or the healers, because people don't want to fight with enemy have unfair advantage, so, they take them too.
30% is way too much. That'd render support classes unable to fight/defend themselves. Limiting classes within a swuad won't help because people will just run solo and field whatever they want. Not that limiting classes is helpful anyway. No one wants to join a battle and be told they can't use the class they've invested in.
Instead of nerfing other classes maybe try buffing the main capping classes to make them more appealing.
There is not much reason to choose melee marine over jetpack one. They need to have a big armor/health bonus so people can choose them over healers and raptors.
The lack of access to high tier weapons isn't enough? I remember the 10% nerf on apothecaries, it sucked. A squad doesn't really benefit from more than two apothecaries, if people can't get organized that's on them. Problem in all factions by the way. Running a sorc and the three guys with you are MoK, or eldar clear a point and there's no DA or warlock.
Having health regeneration would push people into using other classes, it can be a trinket for all i care but needing a healthpack or a Apoth every encounter gets tedious after a while and promotes the deathball even moreso.
Yeah loyalists have shields, and Chaos assault marines have what? Everything they can can be done with a raptor expect capping.
